Guinness Peat Group, the investment firm liquidating its investment portfolio, sold its 30% stake in Britain's Newbury Racecourse for £6.4 million in a share buyback after investors agreed to the deal last week.

The investment firm sold 1.43 million shares at £4.50 apiece in a share buyback approved at a general meeting last week, which the stock subsequently cancelled. The buyback was a 2.3% premium to Newbury's last trading price.

GPG flagged the sale earlier this month as it looks to divest assets and return capital to shareholders.
